| Abstract: | In the paper,firstly we discuss a constructiong method of integer Haar wavelet transform.Secondy Using subblock DPCM and integer Haarwavelet transform,we have odtained the encoding compressive methods of the lossess images,This method are of following some features:(1)the real-time processing of remote sensing are possible for real-time tranmission;(2)hardware implement is easy;(3)the algorithm is of parallel structure;(4)only addition,subtraction and bit-shift is necessary.Lots of experments illustrate that our method is an effective compressive encoding method for images. |
